At present, the vast majority of existing artificial sand production lines adopt wet production technology. Regardless of the form of sand washing machine used, the biggest disadvantage is that fine sand (particles below 0.16mm) is severely lost, and some even lose more than 20%. This not only loses production, but also seriously affects the grading of sand, resulting in unreasonable grading and coarse fineness modulus, greatly reducing the product quality of machine-made sand. Excessive discharge of fine sand can also cause environmental pollution. In order to solve the above problems, our company has successfully developed the XW series fine sand recovery system. This system is designed by our company by absorbing advanced foreign technology and combining it with the actual situation in China. It has international advanced level and is widely used in the recovery of fine particle materials such as mud purification, hydropower station sand and gravel aggregate system, glass raw material processing system, artificial sand production line, and coarse coal slurry recovery in coal preparation plants.

1. Structure: Composed of motor, slurry pump, mud sand separator, ZKR linear vibrating screen, cleaning tank, return bin, etc.

2. Working process: The pump slurry sand water mixture is transported to the mud sand separator. The fine sand that is centrifuged and concentrated is provided to the vibrating screen through the sand settling nozzle. After dehydration by the vibrating screen, the fine sand and water are effectively separated. A small amount of fine sand, mud, etc. are returned to the cleaning tank through the return bin. When the liquid level in the cleaning tank is too high, they are discharged through the discharge port. The weight concentration of materials recovered by the linear vibrating screen is 70% -85%. Adjusting the fineness modulus can be achieved by changing the pump speed, changing the mortar concentration, adjusting the overflow water volume, and replacing the mortar nozzle. Thus completing three functions: cleaning, dehydration, and grading.

1. In the traditional wet processing technology of artificial sand, the washing and dewatering of artificial sand are carried out using a spiral sand washing machine, and the loss of artificial sand (especially fine sand) is almost uncontrollable. The use of this fine sand recovery device can effectively reduce the loss of fine sand, keeping it within 5-10%. It effectively solves the problem of high fineness modulus of finished sand and low stone powder content in artificial aggregate processing systems.

2. The vibrating screen uses polyurethane mesh, which has a longer lifespan and is less prone to clogging compared to other types of mesh.

3. The inner lining of the cyclone is made of polyurethane, which improves the service life of the entire device and can smoothly complete tasks such as slurry concentration and liquid clarification.

4. The fine sand recovery system can recover up to 85% of the fine particulate materials in the total emissions, which has unparalleled technological and economic advantages compared to other equipment.

5. The fine particles are fully recovered, reducing the workload of the sedimentation tank and lowering the cleaning cost of the sedimentation tank;

6. The fine sand recycling system reduces the natural stacking time of fine materials and can be directly transported to supply the market.

7. The fine sand recovery system can be designed with corresponding solutions according to different user requirements.
